Abstract:
This improved carrier allows for drop in type sash installation without having extended features which would preclude the use of wider sash and without having to position the two counterbalances at different vertical positions in order to insert a window sash's pivot bars into the carriers' cam slots. It is also adapted to receive multiple lock elements, wherein the lock elements can be sized to configure the carrier for use in different sized jamb pockets, eliminating the need for manufacturing tooling to produce the carrier component in a variety of sizes. In addition, it has features to retain the cam in its assembled position, independent of the lock, allowing the carrier and cam to be applied to a counterbalance prior to assigning the counterbalance to a particular jamb pocket size. When the particular application for the counterbalance is determined, the appropriate lock element can be readily applied, to properly size the counterbalance system to the application. Finally, this carrier includes retaining features allowing its use in conjunction with a pin having complementary features such that the pin cannot be pulled axially out of engagement with the cam once it is properly positioned therein.
Abstract:
A carrier for a window sash having an actuatable friction adjuster. The friction adjuster has a carrier interface that interacts with a mating friction adjuster interface of the carrier such that the actuation of the friction adjuster by rotating it within an oblong slot in the carrier causes the carrier interface to interact with the friction adjuster interface and forces a rear portion of the friction adjuster into progressively increasing frictional contact with an adjacent portion of a window frame sash channel.
Abstract:
A spring wiper for curl springs contained within curl spring mounts, holders or shoes operatively engaged with window sashes that are located in window shoe channels. The spring wiper is deployed on the curl spring holder or mount and contains a wiper blade that is transverse to the curl spring, spanning its width, in order to wipe or scrape debris clinging to and/or accumulated on the surface of the curl spring exposed to airborne particulate matter when the curl spring is extended prior to its being retracted into the curl spring mount or holder, thereby keeping such debris from entering the inside of the curl spring mount or holder and interfering with the continued fluid operation of the sash.
Abstract:
A window balance system includes a tilt lock carrier connected to a balance for a tilt sash so that the carrier and other components of the balance can be inserted laterally through a slot in a front wall of a balance channel, rather than requiring assembly length wise from an open end of the channel. The preferred way of accomplishing this is by configuring the carrier in a channel shape with spaced apart side walls bearing locking elements and a pivot allowing the carrier to be folded up to straddle a connector or balance in a compact configuration that is laterally insertable.
Abstract:
An insulating composition for use in high voltage devices is formed from a soft dielectric casting compound, such as a silicone gel, comprising ferroelectric particles such as barium titanate dispersed within it. Low levels of particles, from 1% to 20% by volume of the insulating composition, are highly effective yet do not cause excessive thickening of the soft dielectric casting compound when it is in its liquid state. The insulating composition is particularly effective for coating, enrobing or encapsulating alternating high voltage devices such as power electronics devices in order to prevent electrical discharge.
Abstract:
An improved play slide footer is disclosed. The play slide footer maximizes the safety and stability, while minimizing the amount of wobble of the slide.
Abstract:
A microscopic tagging material is provided comprised of a material to which has imparted at least two degrees of identification selected from the group consisting of physical configuration, elemental analysis, functional analysis, and polymeric composition analysis. The material may be a polymeric material, and the tagging material may comprise cut sections of an extruded polymer or polymer composition. The tagging material may be used as an authenticating means for a variety of compositions, coatings and/or products, such as food or drug products.
